hi, i also have fibromyalgia which i was told about 2mths ago. i have been waiting for 9yrs to find out what was wrong with me . im on Gabapentin Ca 300mg which is also called Nupentin 300 it helps but they said swimming, Tai Chi. helps more. stay warm in winter but you have to stay cool in summer as the weather can makes your body worse.
You might ask your dr to let you try Lyrica. You start off at a lower does, then increase it slowly. It helped me with a lot of the muscle spams and pain. But since I am also type2 diabetic, I had to quit taking it as I gained weight on it. I've read that is the main side effect. Neurontin also is good for muscle pain. Good luck, and stay warm this winter. The cold seems to worsen the symptoms.
